Mapping the early universe with NASA's Webb Telescope

Astronomers and engineers have designed telescopes, in part, to be "time travelers." The farther away an object is, the longer its light takes to reach Earth. Peering back in time is one reason why NASA's upcoming James Webb ...

Astronomers to put James Webb Space Telescope through its paces

NASA's latest and snazziest mission, the James Webb Space Telescope (JWST), launched on Christmas Day, deployed its 21-foot-wide mirror a mere two weeks ago and reached its orbital destination earlier this week. With a flashy ...
